Background. Autism is a spectrum of neurodevelopmental disorders with manifestation within 3 years after birth. Manifestations of autism include behavior problems (hyperactivity, toys destruction, self-harm, and agression) and sleep and eating disorders. Etiology of autism is poorly understood. Oxidative stress and antioxidants can participate in pathobiochemical mechanisms of autism. Methods. Twenty-four children, aged 3–6 years, with autism according to the DSM IV criteria and using CARS were included in the study. Concentrations of , γ- and α-tocopherol, β-carotene, and lipid peroxidation were determined in plasma before and after three months of supportive therapy with ubiquinol at a daily dose  mg. Data on behavior of the children were collected from parents at the same time. Results. Ubiquinol supportive therapy improved symptoms in children with autism, as communication with parents (in ), verbal communication (in ), playing games of children (in ), sleeping (in ), and food rejection (in ), with plasma level above . Conclusions. Beneficial effect of ubiquinol in children with autism has been demonstrated for the first time. We assume that plasma concentration of and lipid peroxidation could be used as relevant biomarkers of ubiquinol supportive therapy.
